Distributed installation configuration system and method

ABSTRACT

Distributed installation configuration system and method are provided. The system and method in one aspect collects information about all products and components being installed from a centralized user interface, before the actual installation is performed, regardless of the target machine locations. The collected information is then stored centrally. Thereafter, subsequent installations, whether on the same or different machine locations, access this information for the subsequent installation procedure.

TECHNICAL FIELD

This application relates generally to computer systems, and moreparticularly to distributed installation configuration system andmethod.

BACKGROUND

A suite of computer related products such as the IAM suite of productsthat are used for identity and access management are usually packagedand sold together. Each product in the suite typically has its owninstallation program, which usually needs to be run separately on themachines on which the product is being installed. Installing theseproducts separately may entail following various rules in order for theproducts in the suite to be able to function properly. For example, theproducts in the suite may have interdependencies on one another and assuch, a product may have specific installation rules that depend onwhether another one of the product was installed in a certain way.Accordingly, an installation configuration tool that is enabled toprovide a way for the install programs to interact with one another isdesirable.

In addition, when running each product's installation program, a usermay be prompted for information that the user has already provided inthe course of installing another product in the suite, resulting inredundant efforts on the user's part as well as the system's part.Accordingly, an installation configuration tool that reduces duplicativeefforts during installation of a suite of products is also desirable.

SUMMARY

Distributed installation configuration system and method are provided.The system, in one aspect, includes an installer module operable tocollect information needed for installing a plurality of productcomponents on one or more machines before installing the plurality ofproduct components. A configuration agent module is operable to storeand manage the collected information, the configuration agent moduleoperable to provide data associated with the collected information. Theinstaller module is further operable to determine whether the pluralityof product components are being installed for the first time, and if theplurality of product components are being installed for the first time,the installer module is further operable to create the configurationagent module. If one or more of the plurality of product components wereinstalled previously, the installer module is further operable todetermine a location of the configuration agent module, whether on alocal machine or a remote machine, and retrieve the collectedinformation from the configuration agent module, continue withinstalling one or more of the plurality of product components using thecollected information.

The system, in another aspect includes, but is not limited to, a userinterface module operable to collect information needed to install aplurality of product components on a plurality of machines. A storagemodule is operable to store the collected information centrally and aninstaller module is operable to locate the collected information forperforming installation of at least one of the plurality of productcomponents on at least one of the plurality of machines.

In another aspect, the method includes determining whether one or moreproduct components associated with a suite of products being installedwere previously installed on one or more local or remote machines. Ifone or more product components associated with a suite of products beinginstalled were previously installed, the method includes, but is notlimited to, determining a location of a configuration system agent,retrieving information related to current installation being performedon a current machine from the configuration system agent, obtaining aset of localized information from a user, and installing one or moreproduct components on the current machine using the retrievedinformation and the set of localized information.

If one or more product components associated with a suite of productsbeing installed were not previously installed, the method includes, butis not limited to, obtaining information associated with all productcomponents in the suite of products being installed, creating aconfiguration system agent and storing the information with theconfiguration system agent, and installing on a current machine one ormore product components selected for the current machine using at leastsome of the information.

DETAILED DESCRIPTION

The distributed installation configuration system and method of thepresent disclosure, in one embodiment, allow installation of products,or suite of products, for example, that may be installed distributedamong a plurality of machines or platforms. An example of such a productis IAM (identity and access management) suite of products. An IAM suitemay include a set of common components and a suite of individual pointproducts that use those common components, which may be installed acrossa plurality of platforms distributed in a network of machines.

For instance, a suite of products and their components function togetherto enable enterprises to provision and secure new web services andweb-based applications to their users, as well as securing legacyapplications, whether for customers/partners and/or employees.

The distributed installation configuration system and method of thepresent disclosure, in one embodiment, installs all common components ina suite of products and configures them for initial use, based in parton information provided by the user during the installation process. Thepoint products may be installed by their own respective installers, forinstance, run in standard interactive mode.

Common components refer to a set of products or product subcomponentsthat together make up the core of the a product suite such as the IAMproduct suite. All necessary common components need to be installed forIAM to function properly. The IAM common components are used by the IAMpoint products. Point products refer to individual products that can beintegrated with each other via the central integration point of aproduct suite such as IAM. Each IAM point product makes use of the IAMcommon components. Typically, IAM point products need IAM commoncomponents installed to function at least in an integrated manner.

In one embodiment, an IAM product may include common components that aregrouped into five “machine roles.” Each machine role has a particularfunction in the IAM product suite, and may need several commoncomponents to co-exist to fulfill that role. For example, the fivemachine roles and their respective constituent common components may be:IAM Web Server installed on one machine that may include the commoncomponents such as Apache Tomcat, Java Development Kit (JDK), WAC (webaccess control) Tomcat Agent, and Identify and Access Manager; IAMWorkflow Server installed on one more machines that may include thecommon components such as Apache Tomcat, Java Development Kit (JDK),Admin Object API, Admin Workflow, and Advantage Ingres (double byte);IAM Identity Server installed on one or more machines that may includecommon components such as Admin Server and options, and optionallyDirectory Backbone; IAM Access Server installed on one or more machinesthat may include the components such as WAC/SSO Policy Server, AccessControl Service, and optionally Directory Backbone. Optionally, theremay be a fifth machine role, Directory Backbone installed on one or moremachines that may include the common components such as Directory andAdvantage Ingres (single byte). The Directory Backbone, however, may bepart of the IAM Identity Server or IAM Access Server, and accordingly,may not need a separate machine that is assigned the explicit role ofDirectory Backbone. In one embodiment, the above-described components inthe same role go on the same machine.

An IAM Web Server machine role, in one embodiment, provides a single,web-based interface for administering the entire IAM product suite. Forexample, IAM Web Server includes the Identity and Access Manager (IAManager), a Web-based GUI from which the entire IAM suite may beadministered. Similar functionality present in the various products'existing legacy GUIs may be included in the IAM Web Server machine role.

An IAM Workflow Server machine role, in one embodiment, receivesmessages, for example, that contain requests relating to userprovisioning, from the IAM Web Server. It examines each request andcreates an appropriate workflow process to fulfill the request. Based onthe workflow process it has established, the IAM Workflow Server sendsappropriate messages to the IAM Identity Server. In one embodiment, themessages that the IAM Workflow Server receives from the IAM Web Serverare in native Admin format, for example, a standard CSV format (commaseparated value), and the messages it sends to the IAM Identity Serverare in standard LDAP (lightweight directory access protocol) format. AnAdmin Object API is used to perform translation between these formats.Briefly LDAP is communications protocol that allows a user tocommunicate with a directory service.

An IAM Identity Server machine role receives messages from the IAMWorkflow Server and routes them to the appropriate IAM products, forexample, using the relevant Admin product plug-in. An IAM Access Servermachine role controls user access to the IAM product suite via the IAMWeb Server by performing user authentication and resource authorization.

Directory Backbone refers to a collection of one or more interconnecteddirectory system agents (DSAs) that together provide a unified directoryservice. Directory system agent (DSA), for instance, is the X.500 termfor a directory server, which is a system that holds directoryinformation.

The concept of machine roles defines groups of common components thatare to be installed on the same machine. This does not exclude thepossibility that a single machine can have several different roles. Forexample, a machine assigned the role of IAM Identity Server or IAMaccess server may implicitly function in the role of Directory Backbonealso. Further, in one embodiment, all the roles, can be duplicated overmultiple machines to provide load balancing and failover for thoseroles.

The various machine roles may be distributed as widely as possible. Themachine roles may also be installed on a single machine or any othercombination of number of machines.

Referring to the above-described common components that are part of themachine roles, Apache Tomcat refers to a servlet container thatimplements Sun's Java Servlet and JavaServer Pages technologies. Tomcatis developed by the Apache Software Foundation's Jakarta Project. WACTomcat Agent refers to a WAC (web access control) Service web agent thathelps manage user access via the IAM Web Server, for example, byenabling the IAM Web Server on which it is running, to interact withother servers. Identity and Access Manage in one embodiment is aWeb-based GUI with an extensible architecture that provides a single,web-based interface for administering the entire IAM product suite.

A Directory Service, in one embodiment is a centralized set of tables ofdata, persistently stored, that contains characteristics associated withfiles and other real objects. A directory service also may include theservices that manage the data in the tables. It uses a single namingconvention and can be referred to as a namespace. A Namespace is adirectory service that uses a particular syntax for naming conventions.Examples include, but are not limited to:

-   -   Windows NT: //MyWorkstation/MyName    -   LDAP: //MyServer/C=US/O=MS/CN=MyName    -   NDS: //Planets/O=Mars/OU=DEV    -   NetWare 3.x: //Docs/MyNw3xPrinter

Admin Object API may be an Enterprise Java Bean middleware layer that isused for the SPML (Service Provisioning Markup Language) server. SPML isused for cross-organization control of access control. SPML is XML-basedexpression syntax for the query and exchange of user, account, andresource provisioning requests. IAM Web GUI may be enabled tocommunicate to this layer. Admin Object API provides local and remoteinterfaces to the functionality of products in the IAM suite. This APIhelps clients to interface to API suite of products without having toknow the details of the Admin architecture and LDAP (lightweightdirectory access protocol) server.

Admin Workflow is a component of an IAM product, such as Admin Servicethat manages administrative functionalities. Its function is toestablish an appropriate workflow process whenever a user in theenterprise makes a request that requires any change(s) to be made withrespect to user provisioning.

A router DSA is a DSA that is not connected to a database, but simplyforwards requests to one or more other DSAs. WAC/SSO Policy Server is acomponent of IAM product that provides web access control. An example ofsuch a product is Web Access Control Service. WAC Policy Server providesuser authentication and resource authorization.

The Directory, a directory product, may also include a componentreferred to as DXtools that comprise a flexible set of utilities thatfacilitate interaction with external data systems. DXtools may alsoinclude a subset of database tools for managing the databases such asIngres™ databases, used for the Directory.

The distributed installation configuration system and method of thepresent disclosure, in one embodiment, stores all installationinformation for all the machines into a single or replicated directory,which may then be used by an installation program on other machines toretrieve information needed for that particular installationautomatically. For instance, the distributed installation configurationsystem and method allow a user to answer questions related to a productinstallation, which answers then will be saved in a repository. Thisrepository can be accessed, subject to applicable security controls,from any additional machines at any time. Any installation programsrunning on any other machines can read from this repository and answerthe questions needed for the install to take place on that machine.

In addition, in one embodiment, the information stored in the repositorymay be reconfigured to allow modifications to the first configuration.For example, a user may want to move the installation to other machinesor change settings on a particular machine. In such cases, the user canre-run the installation. Re-running the installation with differentconfiguration will update the information in the repository that wasstored during the previously installation. When the information isupdated with new configuration, the user will be notified of themachines that need to be updated for the new changes to take effect.

Having a repository of installation information reduces repeatedlyasking similar questions and also allows a user to continue with theinstall at any time without having to answer the same questions. In thefollowing description, the system and method of the present disclosurewill be described in conjunction with installing an IAM (identity andaccess management) suite of products, as an example only. Thus, itshould be understood that the system and method of the presentdisclosure is not limited in its use to the IAM products, but rather maybe used to install any other products or suite of products.

FIG. 1 is a system architectural diagram illustrating the distributedinstallation configuration of the present disclosure in one embodiment.A directory system agent (DSA) 114 is created after the installation ofa product suite directory 102 such as a Directory Service, on the firstmachine 104. A directory has a stored collection of users, userpasswords, and usually, information about what systems and services theusers can access and types of policies. Policies are operating rulesthat are used to control access to and priorities for the use ofresources. When the installation has been run all the answers to thequestions, including generic questions for the secondary machines, areloaded into the directory 102 using, for example, JNDI (Java Naming andDirectory Interface) calls. The schema that is used in the directory 102may be customized for the IAM install but can be modified to have anyentry the user desires.

In one embodiment, the directory entries are setup with an attributethat tells the installation on which machines the products should beinstalled or modified. When the installation is run on a secondarymachine 106-112, more JNDI calls gather the relevant information fromthe original machine 104 where the directory 102 was installed. Theinstallation program or module running on the secondary machine 106-11may, for instance, prompt the user, for example, “welcome, we havedetected that you are going to install product A on this machine, pleaseclick next to continue installation.”

The user then only needs to answer local questions such as installationlocation on that machine. The installation program running on thatsecondary machine then installs and informs the user what machine toinstall on next and how many to go. The local questions, for instance,are those that are not included in the first installation process andmay pertain to machine specific information such as operating systemspecific questions.

In one embodiment, rerunning the installation on the first machine 104updates the directory information 102. Using various attributeinformation stored in the directory 102, for instance, a referencecount, the distributed installation configuration system and method ofthe present disclosure, in one embodiment, then determines othersecondary machines that are affected by this update and prompts the userto rerun the installation in those secondary machines as well. Inanother embodiment, the directory may be stored as a part of a separateserver, for example, a web server that can be accessed by a plurality ofmachines or platforms.

FIG. 2 is a block diagram illustrating the components of the distributedinstallation configuration system in one embodiment. The system in oneembodiment includes a product explorer module (PE) 202, an installermodule 204, a configuration directory system agent (DSA) 208, and aninterface layer module 206. PE 202, in one embodiment, is the entrypoint of the distributed installation configuration system. PE 202functions as an initial user interface for the product installation, forexample, IAM installation, and launches the installer module 204. PE 202also may provide links to useful websites so that a user can browsethrough the information presented by the PE 202 before clicking the“install” button, which will launch the installer module 204. UnderWindows™ operating system, PE 202 may be built using the DemoShield™development tool.

In one embodiment, the PE 202 may be enabled to execute individualinstall programs such as the install programs for the IAM pointproducts. In addition, the PE 202 may be enabled to execute apost-installation program that updates the directory information andconfiguration 208 210 (also referred to as IAMConfig) with the relevantpoint product information. This may also trigger another process thatupdates the IAM GUI to include the new point product. Point products areindividual products that can be integrated with each other via thecentral integration point of IAM. Each IAM point product makes use ofIAM common components described above.

The install module 204 is launched by the PE 202 in one embodiment, andprovides a detailed user interface for gathering installationinformation from the user. For example, the installer module 204 may askthe user a series of questions about where and how the user would liketo install the IAM common components. These questions may cover not onlythe products that are going on the current machine, but also allproducts on all machines, giving the install module 204 a suite-wideview of the user's requirements. The install module 204 coordinates thelaunch of black-box installers for the various common components of aproduct suite, such as the IAM common components and configures selectedfiles and/or settings on one or more target machines.

Once the questions have been answered, the installer module 204 caninstall the products associated with the role(s) assigned to the currentmachine immediately. These products, for example, are installed by theirnormal installers, driven in silent mode by the installer module 204.Since the user has already described the overall suite to the installermodule 204, it is able to configure the products it installs with anyinformation each product requires in order to connect to the remoteproducts, which have not yet been installed.

In one embodiment, a first machine on which the PE 202 and the installermodule 204 is run is assigned a role that contains a Directory Backbone,and once the questions have been answered, the installer module 204installs and configures the appropriate machine roles and IAMConfig.Thus, in this embodiment, the IAMConfig is running before the firstinstallation exits, for instance, so that the information about theoverall layout of the suite that the user entered in stored in theIAMConfig.

Information about any other common components that were selected to beinstalled on additional machines are also registered in the IAMConfig.On the second and subsequent machines in the suite, the installer module204 is pointed, for instance, by the user, at the IAMConfig created onthe first machine. This information may then be used to automaticallyanswer the questions on the second and subsequent machines, eliminatingthe need for the user to re-answer questions. The install module 204 maybe built using either InstallShield Developer 8™ or InstallShieldMultiPlatform™ 5.0.

DSA 208 (e.g., IAM Configuration DSA) in one embodiment is created andconfigured by the installer module 204 and is used to store installationand configuration information about the current product setup such asthe IAM setup in a storage 210. For instance, on each machine assignedthe role of Directory Backbone, the installer module 204 sets up the IAMConfiguration (IAMConfig) DSA 208. The IAMConfig DSA 208 will take theinformation gathered during the installation process, for example,ports, hostnames, etc., and store the information using a common schema.

The IAMConfig DSA 208 may contain sensitive information such as theadministrative passwords, which require protection. The IAMConfig DSA208, thus in one aspect, may include password authentication, forinstance, using a password set by a user when the user initially runsthe installer.

The interface layer module 206 is used to communicate between theinstaller module 204 and DSA 208. The interface layer module 206 allowsthe installer module 204 to access the data stored in the DSA 208. Theinterface layer module 206, for instance, makes connections to theconfiguration DSA 208, update and retrieve relevant information neededfor the installation, for example, by the installer module 204. Further,point product individual installer programs may use the interface layer206 to communicate with the configuration DSA 208. The interface layer206 may communicate with the directory system agent 208 either using thecommand-line tool DXTools as described above, or by linking against anLDAP library. In one embodiment, the interface layer 206 also handlesencryption of password information that is kept by the configuration DSA208. A cryptographic library such as PKIs (public-key infrastructure)may be linked against the interface to handle the encryption.

The storage 210 may include any data repository device currently knownor will be known in the future that is capable of storing data. Forinstance, the storage 210 may store directory using a database such asIngres™. Thus, IAMConfig may comprise a DSA 208 and related repository210.

As described above, the product explorer (PE) 202, functions as aninitial user interface and performs such functions as displayingappropriate branding graphics, giving the user overview informationabout the products on the product distribution and installation mediumsuch as the CD, allowing the user to browse the documentation on the CDwithout installing anything, and launching the actual installers. PE 202may be enabled to launch various point product installations, and alsohave an additional function of informing the common components that anew point product has been installed, further automating theinstallation of point products. Under different operating systems suchas UNIX, the product explorer 202 may be skipped altogether and theinstaller module 204 launched directly.

The product explorer (PE) 202 presents a plurality of different screensto the user. For instance, the top-level view displays a brief write-upof what IAM is, and an button to launch the installer module 204. Belowthat, there may be a menu of the various IAM machine roles, and the usercan click on each to get a description of how that role relates to theoverall IAM installation. There are also screens that listdocumentation, which can be browsed, for example, using a documentreader such as Adobe Acrobat™. User may also browse the CD via one ofthe screens provided by the PE 202.

PE 202 also may be enabled to retrieve information about the pointproducts that are installed manually, for example, by communicating witha back end that stored information during the manual install process.

The installer module 204 performs the actual installation of all thecommon component products over multiple machines. FIG. 3 is a flowdiagram illustrating a functional flow of the installer module in oneembodiment that is enabled to install multiple machine role components,for example, of an IAM suite of products across one or more machines orplatforms. During the initial interaction with the installer, the userassigns roles to specific machines, either local or remote. In thisembodiment, one Directory Backbone or a role that includes a DirectoryBackbone (for example, an Identity Server or an Access Server) is beinginstalled on the local machine. Any other instances of the five rolescan be on either the local machine or remote machines. In thisembodiment, the installer collects all the information from the userabout all the common components of products being installed.

Referring to FIG. 3, on launching the first install at 302, a user isasked whether this is a first install at 304. If it is the firstinstall, the user is presented with an installation status screen at306. An example of an installation status screen is shown in FIG. 4.Referring to FIG. 4, the installation status screen 400 shows, forinstance, a list of products or machine roles 402 to install. The list,for example, may be obtained from the product distribution CD. For eachproduct or machine role, status 404 of installation is also shown, forinstance, as completed, half completed, etc. The destinations field 406shows the target machine or machines on which the products are installedor will be installed. The installed field 408 shows the number of theproduct installed. A user may be able to configure a selected number ofproducts or machine roles by, for example, clicking on a “configure now”button 410 associated with the product. In addition, the status screen400 may be set up so that clicking a button or clicking on the productname or machine role would further drill down and display a list ofcomponents that are associated with the product name or machine role.Similar status information would then be shown for the list ofcomponents, as well as an option to enter answers for specificcomponents or configure specific components in the list.

Referring back to FIG. 3, a user may select a product or machine role toinstall from the status screen shown at 306. As part of the installationprocess, the user may select one or more machines or platforms on whichthe user wishes to install each group of products. A single machine canhave several distinct roles, and any role can be duplicated overmultiple distinct machines to provide load balancing and failover forthose roles, with an exception of the Web Server IAM machine role in oneembodiment. During the initial interaction with the installer, the userassigns roles to specific machines, either local or remote, forinstance, using the status screen. For an IAM suite of productinstallation, for example, one server that includes a Directory Backboneis installed on the local machine, and any other servers and anyinstances of the other four roles can be either on the local machine orremote machines. In one embodiment, an Identity Server or an Accessserver machine role is chosen for the local machine.

At 308 and 310, questions relating to a first common component for aproduct chosen to be installed is asked. After answering a question or agroup of questions, an updated status screen may be presented to theuser at 306. Thus, for example, the status screen that summarizes whatthe user has answered and what still needs to be answered may bedisplayed periodically, for instance, between each product's set ofquestions. Optionally, a panel may be provided on the side of the windowat all times to indicate the user's progress against a fixed list ofstages in the installation.

The process of collecting of information for the first common componentcontinues at 308, 310, and optionally at 306. When the informationrelating to the first common component is collected from the user,questions relating to a second common component for the product chosenis asked at 312 and 314 in the similar manner. At 316, the collecting ofinformation continues for the remaining components of the productselected to be installed.

In one embodiment, the installation information needed for a givencomponent or product that can be taken or inferred from answers the userhas already provided in relation to another component or product arereused, thus the user is not presented with a question that the useralready answered. This may be done, for example, by using a schema thatassigns name-value pair data for information already collected. Thus,before asking another question, a determination is made as to whetherthat name-value pair data already has data assigned to it. If so, aquestion about this information would not be asked again.

Once the questions have been answered, all the products that are toreside on the local machine are installed at 318 using the collectedinformation. This may be done, for example, by running the individualproducts' installers in silent mode with appropriate command-lineparameters. For those products to be installed on different machines orplatforms, the installer module may be physically run on multiplemachines individually, in one embodiment. In another embodiment, theproducts may be installed remotely.

After installing the products, in one embodiment, a DSA is set up in theDirectory, for instance, using a directory tool that may be provided byan IAM application, and the information that the user provided to theinstaller is stored in this DSA, available for subsequent installations.DSA may include a process and a database to store information. Forexample, at 320, it is determined whether this is the first install forthis component. If it is the first time this component is beinginstalled on this local machine, Config DSA (DSA configuration or DSA)is created at 322 and the process continues to 324. If at 320, this isnot the first time this component is being installed, the informationcollected from the user and the installation information is stored inthe already created Config DSA at 324. At 326, post-installationconfiguration is performed, if any. Post-installation configuration mayinclude, for example, starting the Config DSA. At 328, the user isinformed of which products are remaining to be installed on whichmachines. A user interface screen may be presented to the user for thatpurpose. For instance, the installer module may display a final screenwhen the installation for the current machine is complete, listing theremaining machines still to be updated. Optionally, the user may beenabled to select automatic remote installation of the products the userselected to install on user selected remote machines.

In the embodiment in which individual installation takes place in eachof the selected remote machines or platforms, the distribution CD may betaken from machine to machine, and for the second and subsequentinstallation, the installer module consults the Config DSA, checks thelocal hostname, and displays a dialog summarizing which products theuser chose to install on this machine. The user only needs to providethe last few pieces of information that was not acquired initially, ifany, for instance, the install location, which is most easily done witha file browser over the local file system, and the products destined forthat machine are then installed. After installation, Config DSA isupdated with the installation information from these machines.

Because the overall plan of what products are going to be installedwhere is chosen before any installation is performed, for example, whenthe user enters the information on the status screen, the installer isable to set up each product with any required information to allow thecommon component products to communicate with one another without anymanual user configuration.

At 330, if it is not the first time the user is running the installmodule, the user is prompted to enter a location, for instance, a nameof the machine and directory, where the machine role having theinitially installed Directory Backbone is installed. At 332, theinstaller module retrieves information saved in the configuration(Config DSA) about the installed components and products from thespecified machine and continues to 306.

Any time during the answering of the questions, for example, at 308,310, 312, 314, 316, the user may stop the installation process andresume answering questions again at a later date or time. In oneembodiment, the answers so far may be saved to a local temporarydirectory. On launching the installer again, the installer checks forthe presence of this saved file and provides the user with an option toload the answers, if present. The user may at that point decide to keepthe answers, or start the answering process over.

In one embodiment, the user may be allowed to change their installationdecisions even after starting to install some of the products in thesuite of products, or even after completing the installation of all theproducts in the suite. In this case, the user is allowed to re-answersome of the questions or provide new information to the installermodule. An option may be provided on a user interface screen for theuser to select to re-answer or provide new information. The installermodule then determines which products are affected by the newinformation. Further, the installer module determines, for instance byusing the timestamp information in the Config DSA, which machines needupdating as a result of the new information supplied by the user. Theuser is then notified which machines need to be updated.

If the user changes the machines on which particular roles are deployed,the Config DSA may again be consulted to determine which configurationinformation for which common components need to be updated. The list ofmachines that need updating are then presented to the user. In addition,the installer module automatically determines the order in which theplurality of products are to be installed as well as calculating theamount of space needed for each installation.

In one embodiment, the user is provided with an option to uninstall thecommon components, for instance via a status screen similar to the oneshown in FIG. 4. If a user attempts to uninstall one of the commoncomponents products individually, the user is given the choice ofuninstalling the entire suite of products or not proceeding with theuninstalling. If the suite is uninstalled, the Config DSA is updated toindicate that every machine requires updating, and the installer guidesthe user to the remaining machines as was done during the installationprocedure.

Configuration directory system agent (FIG. 2 208), also referred to asConfig DSA, holds information about the overall product suite, forexample, an IAM suite of products. This information is made availablefor the installer module to streamline the installation process asdescribed above. The DSA also may store any other information that my beuseful for future applications, such as the information useful fortechnical services to get an overview of the overall suite of products,for instance, when diagnosing problems with an installation.

Some examples of the information collected in the DSA may include, butis not limited to, for each machine role, locations, ports, version,authentication information such as the usernames and passwords, whetherinstalled or not installed, installation options, and name-value pairsas information to feed to the installer module on the second andsubsequent runs.

The DSA contains authentication information for the various products inthe product suite and therefore, may be password protected. The passwordfields may also be encrypted using the DSA password, that is, anotherpassword to protect the data. In one embodiment, any password that arestored in the DSA may be encrypted and marked as octet strings in theDSA. The passwords that are stored in the DSA may include Admin andpolicy server passwords, or passwords for accessing other components ofthe application. They may then be encrypted/decrypted at the user end bythe installer, for instance. In one embodiment, the data communicatedbetween the installer module and the DSA via the interface layer may beencrypted, for instance to prevent unauthorized reads, and signed, forinstance to prevent unauthorized modifications, prior to transmission.

The interface layer (FIG. 2 206), also referred to as Config Interface,sits between the installer module (FIG. 2 204) and the DSA (FIG. 2 208).The interface layer may be implemented as a DLL (data link library)providing custom actions for whatever system the installer module isdeveloped under. The interface layer may also be a shell script wrapperfor a binary such as the Directory binary “dxtools,” or a binary itself.

The interface layer allows the installer module to access the datastored in the config DSA. An example of a syntax for the interface callmay be: assign_iamconfig_data (directory_machine, “INSTALL_LOCATION”,“c=AU, o=CA, ou=IAM, cn=AccessControl”, ‘install_location’). This callcauses the interface layer to read the current value of theINSTALL_LOCATION property, connect to the Config DSA port on theselected machine, and submit the value to the given attribute of theentry with the given distinguished name. Distinguished name refers to aname that uniquely identifies an object in a directory. Thedistinguished name includes the entry's relative distinguished name,plus the names of container objects and domains that contain the entry(an item stored in the directory). Also, the distinguished name uniquelyidentifies an entry's location in a tree. An example of a distinguishedname is: “cn=Peter Smith, ou=Accounts, ou=MyCorporation, c=US”. Inanother embodiment, the installer module may pass string data structuresto the DSA so that DSA can return the string data structures withappropriate values. The installer module than may assign the returnedvalues to variables in the installer module.

In one embodiment, the interface layer is passed the followingparameters: a flag indicating which way the data should flow (from theDSA to the installer module, or from the installer module to the DSA); aURL-style designation giving the machine name and port number where theConfig DSA is running and the “base” Distinguished Name; a stringproviding the distinguished name of the data in the DSA; a username andpassword for the DSA; a string which names the Java bean in theinstaller module to equate with the data in the DSA, for example,depending on the mode in which the interface is called, the values ofthe properties in the bean are transmitted to the DSA, or the DSA isread and the values retrieved are assigned to the bean's properties; alist of properties which should be treated as local, for example, if allother properties are considered to be global.

The interface layer 206 may be written as a Java Bean and have access tothe JNDI (Java Naming and Directory Interface) to perform the LDAPcommunication with the DSA 208. When reading from the DSA 208, theinstaller module 204 may use the parameters passed in by the interfacelayer 206 to fetch both the global entry for a given product and thelocal entry with the same common name (cn) as the current hostname, andmerges the data into a single value of each attribute, taking globalattributes from the one and local attributes from the other. Theseattributes are then assigned to the nominated Java Bean.

When writing to the DSA 208, the reverse occurs. The interface layer 206reads the current values of the various properties from the nominatedJava Bean, and creates two modify requests, one applicable to the globalentry and one applicable to the local one.

FIG. 5 is a flow diagram illustrating the distributed installationconfiguration method in one embodiment. At 502, the product explorer islaunched, for example, when a product CD is inserted into a machine. Theproduct explorer allows the user to read information about the commoncomponents in the product suite and the documentation about the productsuite, in one embodiment. The product explorer, for example, may displayappropriate branding graphics, provide the user overview informationabout the products on the installation disk, allow the user to browsethe documentation on the installation disk without installing, andlaunch the actual installer. Two main options on the product explorermay include: 1. install a read (for use with the documentation); 2.launch the installer module. The product explorer, in one embodiment, isa centralized information area to help the user to get familiarized withwhat the product suite is and how it can be configured and installed.

The product explorer may present a number of different screens to theuser. At any point, the user may click the install option to launch theinstaller module. In one embodiment, the top-level view displays a briefwrite-up of what IAM (or any other product suite) is. There may be anoption to display information about the various IAM machine roles, andthe user may click on each to get a description of how that role relatesto the overall IAM installation. There may also be screens where thedocument is listed and can be browsed, for instance, using a third partydocument reader. The user may also have an option to browse the CD.

The installer module performs the actual installation products over themachines nominated by the user. On launching the first install,information about all the common components for a product suite issolicited from the user. As part of this process, the user may nominateon which machine(s) to install each group of products.

For instance, at 504, when the user launches the installer module, theuser will be presented with a screen asking if the user wishes toinstall the suite of products on just the local machine, or on multipleboxes. If the user selects multiple boxes, the user is further presentedwith a screen asking if any of the suite of products were installedpreviously, and if so, to enter the location of one of their directorybackbone machines, for example, the machine on which the user startedthe installation process.

The installer then proceeds to one of several possible views, dependingon the context. If the user indicated that no previous installation wasdone, the user is asked a plurality of questions, ahd the installationprocess begins with those products that can be installed on the localmachine at 506.

After installing, a DSA (“IAMConfig”) is set up in the Directory, andall the information that the user provided to the installer is stored inthis DSA, available for subsequent installations. The Directory, forinstance, is installed as part of the installation process in thecurrent machine, for example, so that the Directory service is availableto provide a place for all the information the user has entered to besaved before the first run of the installer module exits.

If the user has previously started installing the same suite ofproducts, the installer module fetches information from the Config DSAat 508 and the user is presented with the status screen showing thecurrent status at 510. If the products in the suite have not beeninstalled on the current machine or the installer module determines thatthe products installed on the current machine need updating, the userhas the option to proceed with that stage of the installation or updateat 512.

From the status screen, the user may have an option of modifying theinstallation by changing the previously supplied answers regarding anyor all of the products. This may result in products needing to beupdated on one or more machines. The installer module automaticallydetermines whether machines need to be updated based on the newinformation and prompts the user accordingly.

The user is also provided with an option to uninstall the entire suiteof products. When the user selects to uninstall, the user is guided toeach machine upon which the un-installation “update” needs to beexecuted. In addition, the installer module may be enabled to installupgrades and patches to the installed product and also update theinformation stored in the Config DSA accordingly.

As described above, the DSA holds, inter alia, information about eachproduct installed in the suite. The specific data fields may bespecified in a custom schema. In one embodiment, this schema may definea single object class, “commonComponents,” and an auxiliary object classfor each product which extends the base commoncomponents class to alsocontain the product-specific data. The data defined for thecommoncomponents object class may include, but is not limited toHostnames, Version, installLocation, commonName. The data defined forthe commoncomponents object class may also include: ToBeUpdated,ToBeRemoved, Documentation, DateInstalled, AdditionalInfo,InstallUserName, InstallOrganization, PatchLevel, ProductDependencies.

Particular fields of both the commoncomponents and auxiliary classes arenominated as either global or local by the interface layer, for example,when it is loaded or read. This distinction is made to determine if asingle value applies for every installation of a given product acrossthe entire suite (such as Hostnames, the list of every machine in thesuite on which this product is installed), or may be different for eachindividual machine's installation (such as installLocation, the locationon a given machine's file system where the product is installed).

In one embodiment, global information for a given product is stored inan entry of the appropriate object class. For example, an Admin server'sglobal information is stored in the entry with the distinguished name ofcn=IAMAdminServer-global, ou=IAM, o=CA.

In one embodiment, local information is stored in multiple entries, onefor each machine upon which the product is installed. These entries arenamed by their product name and machine in one embodiment. For example,the entry describing the local information pertaining to the AdminServer on the machine QA59805.ca.com would have a distinguished name ofcn=qa59805.ca.com, ou=IAMAdminServer-local, ou=IAM, o=CA.

In one embodiment, information appears in both the global and localentries because they are of the same object class. In one embodiment, itis up to the interface layer to decide which piece of data applies to aparticular machine. Thus, the distinction is associated with thatcomponent. The interface layer fetches both the global entry for a givenproduct and the local entry with the same common name (cn) as thecurrent hostname, and merges the data into a single value of eachattribute, taking global attributes from the one and local attributesfrom the other.

In one embodiment, some information may apply to entire roles ratherthan individual products. The Hostname is one example. Since allproducts that are part of a given role may be installed together, thelist of machines that a given product has been installed on can beinferred by looking at the lists of machines that the roles that productis part of have been installed on. For convenience, one product in eachrole may be chosen to represent the entire role.

The system and method of the present disclosure, in one embodiment,allows a user to answer questions about an install, which is saved in arepository. This repository can be accessed, for instance, subject toapplicable security controls, from any additional machine at any time.An installer module can then be run on any other machine and will readfrom this repository and automatically provide answers needed for theinstall on that machine. The repository further may store otherinformation needed for matters other than installing.

The system and method of the present disclosure may be implemented andrun on a general-purpose computer. For example, the system and methodmay be implemented as a set of computer instructions to be stored oncomputer memory units and executed on the computer processor. Theembodiments described above are illustrative examples and it should notbe construed that the present invention is limited to these particularembodiments.
